There are some projects that only one country can build! And in those decades, you really don't know how many such projects have been built in China, it was a great era, and it was also an era of sadness, an era of heroes.

Han Shuang silently looked at the entire huge passage, which should have been developed according to some secret hangars, so these passages were very wide, such a project was unimaginable in that era.

Because in that era, it was purely chiseled out little by little, you can't imagine how much manpower and material resources are required for such measures, and there are shield machines for building a tunnel in modern times, but there are no shield machines in that era.

On the tunnels on both sides, you can even see the paint color that is very characteristic of that era, as well as some slogans, but those slogans have been mottled and can only be faintly seen a few words, which are now incomplete.

But as you can guess, these are very characteristic things of the times, but because this is just a passage, there is no need to deal with it, so it is allowed to be weathered by itself.

Further inside, the passages on both sides finally showed signs of being treated, and after driving a little further, their convoy stopped directly, "This is a huge lift, let's go directly underground." Liu Lao explained.

Han Shuang nodded silently, such a huge hydraulic lift is also a reflection of a country's strength.

As a low "buzz" sounded, a low roar accompanied the ground as it began to slowly descend, and huge cracks immediately appeared on either side of them. Looking at this huge lift, it is clear that there is no problem in letting a fighter jet descend directly.

In fact, after the elevator came down, Han Shuang and the others saw the fighter, the area here was already large enough, and it was obviously not easy to find a place larger than this area in the mountainside.

However, it is estimated that it has been dealt with separately here, and there should be an up and down passage here.

After the elevator completely landed, the vehicle drove down directly from it and stopped directly, Han Shuang and they got out of the car, less than 20 meters away from Han Shuang and Xia Ke to the left, and the unmanned fighter they had seen had already parked there.

They walked directly in that direction with Professor Liu, and when they walked over, Han Shuang and the others found that the cockpit of the drone had been opened from below, and a spherical object had been removed from it.

Seeing this familiar scene, Han Shuang suddenly reacted to where this thing came from, wasn't this the drone in the top-secret flight? Han Shuang really hadn't guessed it before, and the ghost knew what this thing was, but when she saw it now, she probably remembered it a little.

However, the content of which TV series, Han Shuang doesn't know at all, the only thing she probably remembers is that this drone seems to have been struck by lightning, and there was a little problem, but on the whole, it is still within the control of people.

Compared with the artificial intelligence she knows, such as Skynet, Wiki, Matrix, Red Queen, Ultron and other famous artificial intelligence, which destroys the world at every turn, this drone can only be said to be far worse than its kind.

Because it still operates within certain rules, and to some extent it has not evolved real feelings, only partial emotions, and when it goes wrong, it is also because it wants to carry out a plan that is originally virtual, but it is regarded as "real", and that's it.

In fact, the main reason is that there is a certain problem with its logical operation, and it is too far from the same kind that has become its world-destroying kind.

Of course, it has to be said that it also has a strong cyber intrusion capability, although this is done based on the United States, to which it belongs, the world's leading Internet in the whole world, but it is also very powerful.

This means that not only does it have a huge amount of storage space, but it also has computing power that is far beyond supercomputing.

"Let me give you a general introduction to our current understanding of it, first of all, its fuel is not our common aviation kerosene, but a special formula of catalytic methane, we have extracted all its fuel, and then conducted research and analysis, there should be no problem in reverse engineering."

"Its main structure is a metal porcelain composition, aeroelastic wings, pulse detonation plus double hybrid supersonic turbine ports, and there are a lot of sensors around its fuselage, the performance of these sensors is very strong, according to our preliminary detection, its detection distance is at least seven or eight kilometers."

"The most important thing is that these sensor detectors not only have a long detection distance, but also their accuracy, clarity and signal transmission speed are very fast!"

"What's more critical is its computing core, which is based on a real quantum computer, and its information transmission speed is about 10TB per second, and the computing speed has far exceeded many supercomputers, and all of this is on the core brain, which is almost the size of a basketball."

"This computing core is something we're almost impossible to build now compared to the other aspects of its fuselage, but it points us in the right direction." Professor Liu told Han Shuang about the current situation.

"By the way, there's something we have to thank you for." Professor Liu's tone suddenly became weird, and at the same time, his eyes were also looking at Han Shuang.

"What?" Han Shuang was a little baffled.

"Come and see." Professor Liu led Han Shuang directly to its wing part, and when he came to the bottom of its wing, everyone immediately saw a circular hole, which was extremely conspicuous, and this hole looked as if it had been shot out by a bullet or an aerial cannon.

But Xia Ke and the others definitely didn't attack this drone.

"We detected a badly deformed bullet inside, which was stuck in the metal structure inside, and it was only able to be removed during later maintenance." Professor Liu looked at Han Shuangdao with a strange expression.

"If I'm not mistaken, this 12.7mm bullet must have come out of your gun, right? We looked at the video from the scene, and the moment it came out of the chasm, you instinctively raised your gun and shot. Professor Liu's tone was weird.
